This paper examines the thermal characteristics of multilayer TiO2/8YSZ coated and uncoated carbide cutting inserts. Turning tests were conducted on a carbide insert at a cutting depth of 0.1 mm, four cutting speeds 88, 112, 141, and 172 m/min, and two feeds 0.065 and 0.265 mm/rev. Measurements were made of tool life, flank wear breadth, and temperature variations at the insert tip. It has been demonstrated that the multi-layer coating significantly reduces flank wear and temperature during cutting. The life of the inserts was doubled by the performed coating. Grey Relational Analysis (GRA), based on the Taguchi Method was used to investigate the impact of coatings and turning conditions on cutting performance. The best possible rating for the grey relationship category was 88m/min, and 0.065 mm/rev.
